I got the Rs.50 puncture done - the first time and then again today morning.

I've not yet seen any doing the second type of puncture repair on tubeless tyres here in Gurgaon or Delhi - generally speaking, since I've not explored tyre repair shops in detail.

i am told there is a more expensive fix which is done from INSIDE the tire using some costly machines and the net result is a small cylindrical tube of rubber sticking out from inside. this costs Rs250 ( in chennai atleast ) and my guess is this is a better fix to punctures than the one available in many small shops here in Gurgaon

Puncture has been re-repaired as you can see in the OP. I'm loathe to putting a tube. I tried calling him but couldn't get through. Hope he reads it here

Have you tinkled Ishaan ?

Thanks Tanveer

I think the problem could be a defective puncture repair kit.
You can also go for path repair, where a patch is stuck on the inside.

How do you do the old fashioned way in a tubeless?

In the 70s the push in 9external) repairs were only considered temporary and we good for at most 100 miles. Proper repairs were supposed to be what I have outlined above

If the pressure loss is detected again then I will visit..Thanks..

Sometimes when the puncture is a little big it happens. The right way to repair this is getting a mushroom patch from the inside. If you drop into any of the Michelin priority partner or a bridgestone select showroom in your city, they'll be able to solve it for you. Its a regular phenomenon.

Yes Narayan, will do so if the problem remains unsolved. Thanks mate.

Dear all - in my opinion, there are two "correct" ways and one "not-preferred" way of repairing punctures in tubeless tires. The two correct ways are as follows:

1. Install a mushroom bung from inside the tire: to do so, it is necessary to remove the tire from the wheel rim, remove the foreign object from the tire, cut a hole of minimum diameter through the tire carcass either by using a very small drill or a thin hand held taper reamer, roughen the inner surface of the tire to increase the friction between the tire and bung to allow the bung to adhere perfectly, choose the correct diameter bung suitable for the application, apply air-drying sealant to the interface of the bung with the tire, insert the bung guide through the carcass till the bung sits concentric with the hole, pull the bung guide through the carcass and hold it for around 1 minute to allow the initial seal to form, let the assembly cure for around 10 minutes (means leave it alone), pull the bung guide again, keep it pulled and at the same time apply a little air drying sealant to the shaft of the bung guide which is protruding from the tire, let it cure for around 10 minutes and then cut the bung guide. Assemble the tire on the wheel rim in such a way so as to ensure that the affected section is the intital portion of the tire going on the wheel rim, so as not to unduly stress this section which happens when the last bit overrides the rim and goes in place. Fill air in the tire upto 80% of the normal tire pressure which should be sufficient to ensure that the bead has located concentric to the wheel rim, remove the air and fill it again exactly upto the recommended tire pressure. Check the pressure with a digital gage and cross-check with another digital gage to eliminate gage error. Balance if required, it is not compulsory to do so if the removed and mounted orientation is the same. Mount the wheel assembly on the car, lower the jack, let the tire take the load of the un-laden car, check for any increase in the projection of the bung outside the tire periphery due to the load on it now and cut-off any small projection, check tire pressure again with the tire on the road, it will be approximately 1psi less than that checked on the assembly machine. Fill the tire to the recommended tire pressure. Check tire pressure and correct in 3 other tires also, without fail. The whole thing takes around 1 hour to do, operator attitude and motivation are very important to do this properly, otherwise it will not get done properly. Cost should be around 300 rupees.

2. Vulcanize the tire in this area: I shall give the details shortly.

Obviously the "non-preferred" way is to have the thread inserted from outside, sticking out of the tire. I am not comfortable with it.

Any pointers to a reasonable honest shop for tire punctures in Gurgaon.

Even though punctures not being a frequent event, but every time a defective nozzle showing up on a punctured tire is driving me nuts. I am fed up of keeping an eagle eye and haggling with these crooks every single time I have to visit one. For the sake of mental satisfaction, I don't mind driving 10km to a relatively honest man with reasonable work quality rather than messing with these shams on petrol pumps under the tag "puncture man".
